Jacob Magar cc24f1ec62 feat: add API key bearer token authentication
- ApiKeyVerifier(TokenVerifier) — validates Authorization: Bearer <key>
  against UNRAID_MCP_API_KEY; guards against empty-key bypass
- _build_auth() replaces module-level _build_google_auth() call:
  returns MultiAuth(server=google, verifiers=[api_key]) when both set,
  GoogleProvider alone, ApiKeyVerifier alone, or None
- settings.py: add UNRAID_MCP_API_KEY + is_api_key_auth_configured()
  + api_key_auth_enabled in get_config_summary()
- run_server(): improved auth status logging for all three states
- tests/test_api_key_auth.py: 9 tests covering verifier + _build_auth
- .env.example: add UNRAID_MCP_API_KEY section
- docs/GOOGLE_OAUTH.md: add API Key section
- README.md / CLAUDE.md: rename section, document both auth methods
- Fix pre-existing: test_health.py patched cache_middleware/error_middleware
  now match renamed _cache_middleware/_error_middleware in server.py

Unraid MCP — Troubleshooting Guide

Credentials Not Configured

Error: CredentialsNotConfiguredError or message containing ~/.unraid-mcp/.env

Fix: Run setup to configure credentials interactively:

unraid(action="health", subaction="setup")

This writes UNRAID_API_URL and UNRAID_API_KEY to ~/.unraid-mcp/.env. Re-run at any time to update or rotate credentials.


Connection Failed / API Unreachable

Symptoms: Timeout, connection refused, network error

Diagnostic steps:

  1. Test basic connectivity:
unraid(action="health", subaction="test_connection")
  1. Full diagnostic report:
unraid(action="health", subaction="diagnose")
  1. Check that UNRAID_API_URL in ~/.unraid-mcp/.env points to the correct Unraid GraphQL endpoint.

  2. Verify the API key has the required roles. Get a new key: Unraid UI → Settings → Management Access → API Keys → Create (select "Viewer" role for read-only, or appropriate roles for mutations).


Invalid Action / Subaction

Error: Invalid action 'X' or Invalid subaction 'X' for action 'Y'

Fix: Check the domain table in SKILL.md for the exact action= and subaction= strings. Common mistakes:

Wrong Correct
action="info" action="system"
action="notifications" action="notification"
action="keys" action="key"
action="plugins" action="plugin"
action="settings" action="setting"
subaction="unread" subaction="mark_unread"

Destructive Action Blocked

Error: Action 'X' was not confirmed. Re-run with confirm=True to bypass elicitation.

Fix: Add confirm=True to the call:

unraid(action="array", subaction="stop_array", confirm=True)
unraid(action="vm",    subaction="force_stop", vm_id="<id>", confirm=True)

See the Destructive Actions table in SKILL.md for the full list.


Live Subscription Returns "Connecting"

Symptoms: unraid(action="live", ...) returns {"status": "connecting"}

Explanation: The persistent WebSocket subscription has not yet received its first event. Retry in a moment.

Known issue: live/array_state uses arraySubscription which has a known Unraid API bug (returns null for a non-nullable field). This subscription will always show "connecting."

Event-driven subscriptions (live/notifications_overview, live/owner, live/server_status, live/ups_status) only populate when the server emits a change event. If the server is idle, these may never populate during a session.

Workaround for array state: Use unraid(action="system", subaction="array") for a synchronous snapshot instead.


Rate Limit Exceeded

Limit: 100 requests / 10 seconds

Symptoms: HTTP 429 or rate limit error

Fix: Space out requests. Avoid polling in tight loops. Use live/ subscriptions for real-time data instead of polling system/metrics repeatedly.


Log Path Rejected

Error: Invalid log path

Valid log path prefixes: /var/log/, /boot/logs/, /mnt/

Use unraid(action="disk", subaction="log_files") to list available logs before reading.


Container Logs Not Available

Docker container stdout/stderr are not accessible via the Unraid API. SSH to the Unraid server and use docker logs <container> directly.
